FLYING-MACHINE.

Specification of Letters Patent.

Patented Aug. 23, 1921.

Application filed October 8, 1920. Serial No. 415,526.

To all whom it may concern: 0

Be it known that I, VVnNznL HAU T, citizen of the Republic of Czechoslovakia, residing at city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Flying-hlachines, of which the following is a specification. Y

The present invention relates to flying machines f the helicopter type and has for its principal object to provide a construction in which the action of the volume of air displaced by propellers on planes arranged at an angle below the propellers is effectively utilized for propelling, supporting and steering the machine.

Another object is to so constructand ar-' range the planes and propellers in relation to each other and to the machine as to enable the latter to start its horizontal or vertical flight without first taking a run on the ground; to carry out its horizontal flight close to the ground at moderate speed and a safe landing; g

The principle on which my invention is based is that when below and coaxially with a revolving propeller a second independently movable propeller is arranged then the volume of air displaced by the upper propeller will cause the lower one also to re volve. If the two propellers are of the same kind, that is to say, both right hand propellers or left hand propellers, then the lower propeller will revolve with the upper one in the same direction and approximately the same speed. But when the two superposed propellers are of different kind, one a right propeller and the other a left propeller, then the lower propeller upon the rotation of the upper one will be caused to revolve 1n opposite direction to the upper one and with a somewhat reduced speed. I

If, now, an inclined plane is substituted for the lower propeller, then this plane Wlll be influenced by the rotation of the upper propeller in two ways, to wit, one half of said plane under the influence of one of the blades of the upper propeller Wlll tend o revolve in the same direction and with the same speed as the upper propeller and th other half of said plane under the lnfluence of the opposite blade of the upper propeller will tend to revolve 1n opposlte direction and with a somewhat reduced speed. The result of such double influence will be that th plane will tend to carry out a lateral operating with an inclined plane arranged below the same.

In accordance with this principle my invention consists in the construction of a flying machine .in which at least two horizontal and oppositely revolving propellers cooperate with planes suspended below the same so as to be adjustable vertically under various angles, so that on proper adjustment, 1

these planes will be acted upon by the air pressure or air volumesdisplaced by the revolving propellers to cause the flying machine, according to the heretofore explained principle, to carry out a horizontal flight.

Upon adjusting the planes into a vertical position they will offer no resistance and the propellers themselves will produce a vertical flight. 1

My invention also consists in the provision of additional planes,for balancing, and steering, as will be hereinafter more fully described and defined in the appended claims.

In the accompanying drawings in which similar reference characters denote corresponding parts, Figure 1 is a more or less diagrammatic perspective view of my improved machine; Fig. 2 is an enlarged top plan view of one end of the flying machine; Fig. 3 is an enlarged vertical cross section thereof; Fig. 4 is a digrammatic front view of the machine showing modified driving planes; Fig. 5 is a diagrammatic end view ofthe machine illustrating the relative ar rangement of the propeller, driving planes and steering or balancing planes; Fig. 6 is a similar end view showlng a modified avrangement of the driving planes and the steering or balancing planes; and Figs. 7, 8, 9 and 10 are similar end views showing other modifications of said planes.

l0 denotes a skeleton substantially rectangular frame composed of wooden rods, metal tubes, or other suitable material with central vertical extensions 10 to form legs which preferably are provided with wheels.

Extending longitudinally and centrally relative and fixed to the upper face of the frame is a supporting beam 12 carrying the bearings for the propeller shafts 17 as will object is to prevent a sudden and rapid fallbe herein-after described. space 14 of the frame serves for the accommodation of the drivers seat 15, motor or motors 16 and all mechanism for controllingthe operation of the different planes and de vices to be presently described (Fig. 3).

For the proper operation of the machine at least two propellers are required, one on each side of the central compartment or space 14. The propellers may be of any known construction, but I have found that a propeller with a plurality of wings or blades, preferably, one of the type described and shown in my copending application, serial #368204 is more advantageous because of the more effective distribution of air in the circular area described by the revolving propeller and because the tendency of bending or breaking of the latter is considerably lessened.

Cooperating with the vertical spindles 17 of the propellers 18, which spindles'are rotatively and suitably mounted in bearings provided in the beam 12, are means for braking and'locking said spindles, whose of the flying machine when the motor fails to operate. Without this brakin and looking means, when the motor or other driving power ceases to operate, the propeller by its own inertia, will first continue to revolve in the driven direction. then, owing to the air pressure acting on it from below, as the machine is sinking, will gradually come to a standstill and thereupon begin to revolve in the direction opposite to the driven direction, thereby causing the machine to sink more rapidly. By the use of the braking and locking means, whereby,

,at the instant the motor ceases to operate,

a brakin action is first applied to the propeller s afts thereby speedily bringing them to a standstill and then locking the propellers the sinking of the machine will be retarded.

Various means may be employed to accomplish this object. In the present embodiment of my invention I have shown these means to consist of a disk 20 mounted onand fixed to each of the propeller shafts 17 below the propellers 18, and provided with diametrically opposed notches 20, and of two spring actuated pawls or dogs '21 adapted to cooperate with said disk and pizotally su m 12. ,T ese do or pawls are arranged at opposite sides o hedisk and are linked together by a member 22, so that the pawls of each pair will. move together. The manipulation of these pawls may be effected by means of wires, cables 23, or the like guided over (pulle s 24 supported in the frame 10, an lea ing to the drivers seat to mani ulated there by a pedal 25 or the like. T e shaft 17 of each propeller is The central ported at 21} on the supporting equipped with the aforesaid device and the two devices may be suitably connected to allow of their simultaneous operation or each may be operated separately.

Normally, that is when the motor is in operation the pawls 21 are held against the action of their springs out of engagement with the notched disks 20, so that the disks while revolvin will be free of friction.

A further ei ect of the locking of the propellers will be that the latter when arrested will act as supporting planes and as such will be more or less effective according to the size and the number of blades composing the propeller. Multiple blade propellers naturally will have a greater supporting efl'ect.

Owing to the fact that the braking and locking of the propeller produces a torque or turning moment which will tend to swing the flying machine around its own axis, it is obvious that this device can be used only when at least two propellers are em loyed each equipped with such device.

1' rranged immediately below each of the propellers 18 are the driving planes 25. These planes are supported in the lateral parts of the frame to be adjustable on horizontal axes. The driving planes may be of any' suitable construction and shape, and their arrangement in the frame and the manner of their suspension may vary according to requirements. In the case, when it is desired to utilize the driving planes both for driving and supporting, four planes may be provided, two for each propeller arranged in pairs, one pair in front and the other pair at the rear of the machine. Each of said pairs of planes is supported on a common horizontal spindle 26, 26', (Figs. 1 and 3).

The planes may each be equal in length to the diameter and in width may range between the width of the propeller blade and the length of a line drawn from one .end of a propeller at an inclination of 45 toward the vertical axis of the propeller. The spindles 26, 26 to one another and at the same elevation below the propellers.

The planes may be made of any suitable material. I prefer to construct each of a wooden frame 26" covered on both sides with canvas 26 or the like. (Fig. 3).

Instead of using planes extending .throughout the entire; length of the ropellers it is possible toilse planes 25 of ialf the size, that is to say. planes of the length of a propellerblade. In such case I prefer to arrange the planes on the inside of the machine or in other words on the sides near the central part of the frame, as shown in Fig. 4.

According to the principle described on page 1, this arrangement of the driving are arranged parallel planes will produce the best driving results when the driving planes are adjusted to the,

. same direction as that of the propeller blades located above them. a 1

Instead of usin two planes for each propeller, a single p ane, preferably the front plane may be used and this applies both to the full length planes and to the half length planes. In this case the machine willbe inclined forwardly while in horizontal flight and develop a greater speed. It may be also advantageous to support the planes on a central spindle 26*, (Figs. 6, 8) or to provide several planes 25 on separate spindles 26 located at the same elevation below the additional planes which'I shall call balanc-' ing planes. These additional planes I prefer to arrange below the driving planes and preferably 1n the middle between the two planes 25 or 25 used for each propeller, as shown in Figs. 1 and 2. The balancing planes 27, of which there is one on each'side,

and which may be constructed similar to the driving planes, are su ported on a common longitudinally extendlng rotary spindle 28 extending parallel to, but somewhat below the spindles 26, 26', and suitably supported in the frame 10. These planes 27 approximately may be of the same size as the driving planes 25 or 25. By turning the spindle 28 the balancing planes 27 may be adjusted at a suitable angle of inclination, which for the horizontal flight, should be somewhat smaller than the angle of inclination of the drivin planes. But the angle of inclination 0 the balancin planes also depends upon various other lnfiuences, such as an unequal distribution of theload, etc.

WhileI prefer to arrange these balancing planes centrally between these drivingplanes, other arrangements, may be found advantageous. Thus the balancing planes 27 may be sus ended from a spindle 28' .extending over t e front or rear faces of the fram (Fig. 7) or the balancing plane 27 may be suspended from the same central spindle 26 carrying the driving planes 25, when a single plane is used for each propeller. In this latter case the balancing planes must of course be capable of inde pendent control and therefore must be independently movable, (Fig. 8). g

The balancing plane may also be fixed to the driving plane 25 to form an extension thereof. In such case the said balancing planes 27 must be made Wholly or partly flexible, yielding or elastic, so-that they may be bent or curved into the desired inclined positions occupied by the driving planes as indicated by dotted lines in Fig. 6.

The balancing planes may also serve for steering the machine laterally, as will be hereinafter more fully described.

The balancing planes 27* (as shown in Fig. 5) may be suspended centrally instead of at their edges, so as to extend on opposite sides of their spindles similar to the driving planes shown in Fig. 1.

In addition to the driving planes and balancin planes I provide longitudinally adjustabIe planes 29, one at each side of the machine, which serve for the balancing of the machine laterally. These planes are slidably mounted on lateral projections 10 extending from the upper part of the frame along longitudinal guide rods 30 supported on the frame and are actuated by springs 31, the tendency of which is to normally press said planes into their extreme outer position away from the revolving propellers so as to be inoperative. Whenthe machine has the tendency to tip on any one of its sides, then the plane 29 on the opposite side is, against the action of its springs, pulled inwardly or toward the center of the machine until it assumes a position directly below the corresponding revolving propeller, so that the volume of air displaced by the latter will be caused to act against it, as a result of which the equilibrium of the machine will be reestablished. These steering planes 29 may be controlled from the drivers seat by wires 29 or the like running over pulleys 29 V These planes 29 may also be usedfor steering the machine laterally. For, by ad justing one of these planes 29 into operative position to be acted upon by the propeller above it, the machine will be lowered on the.

corresponding side, in consequence of which the speed on that side will be somewhat re duced, causing the machine to turn toward the inclined side. I

For assisting in rapid steering in addition to the above planes vertical rudders (not shown) of well known construction may be used.

The lateral steering may also be assisted by the heretofore described driving planes, when the driving planes on the two sides are arranged to be adjustable independently of one another, so that the planes on one side of the machine may receive a greater or smaller inclination than on the opposite side, or may be brought into a vertical position, while the planes on the opposite slde are retained in their inclined position. Owing to the greater resistance on. the side of the greater inclination of the planes, then 'be effected by adjusting the on the opposite side the machine will be caused to turn toward the latter side.

The propeller shafts 17 are driven from the motor 16 in opposite directions throu h the medium of a suitable transmission mec lianism M.

The control of the adjustment of the driving planes from the drivers seat according to the present example is accomplished through chains 37 or the like transmitting motion to cross spindles 38 which in their turn transmit motion by bevel gears 39 or the like to the shafts of the planes. The shafts of the balancing planes may be operated through gears 40 or the like.

The mode of operation of my machine is as follows:

Assuming thebalancing planes and the driving planes to be adjusted in vertical position, and the lateral steering planes 29 at the extreme end positions, then the 'propellers,whenset in motion to revolve in opposite direction, will bring about a verticab flight. B

y adjusting the driving plane or planes for each propeller at a suitable angle of inclination. preferably 45, and the balancing planes at preferably 23 while leaving the lateral steering planes in their extreme end posi- Eons, the machine will carry out a horizontal lght.

If it is desired to stop the machine in the air the front and rear driving planes when using the construction shown in Figs. 1 or 5 are adjusted to extend in opposite directions to one another, until such strong resistance is created, that the machine will sto "hen the motor ceases to operate,- the propeller shafts are locked in the above described manner, the driving planes brought into horizontal position. The planes 29 in this case may be used for lateral steering, while the driving planes and balancing planes, for horizontal steering.

Landing in vertical direction may be effected by lessening the driving power or the angle of inclination of the driving planes, or both.

Landing in horizontal direction may be effected by proper adjustment of the steering planes.

To start a horizontal flight directly from the ground without first taking a run can driving planes at an angle of about 45.

When employing the plane arrangement shown in Figs. 1 and 5 it may be advantageous to adjust the rear pair of planes at an angle somewhat smaller than that .of the front planes.

In case two motors are provided, it is preferable to arrange these motors at the sides of the drivers seat, one on each side.

If, during the horizontal flight, it' is dean angle somewhat smaller,

sired to also rise radually, then the angle of inclination of the balancing planes from the vertical is somewhat reduced or that of the rear driving planes increased relative to the propellers, in consequence of which the air pressure acting against said planes will cause the flying machine at the front to assume an upwardly inclined position, which will result in a gradual ascent.

\Vhile I have described details of construction it is understood that various modifications may be made without departing from the spirit of my invention and I, therefore, do not wish to limit myself to the construction shown and described.
